An English rock band active in the Ladbroke Grove underground and psychedelic scene of the early 1970s. They promoted free music, drug taking and anarchy and often performed impromptu gigs and other agitprop stunts, such as playing for free outside the gates at the Bath and Isle of Wight pop festivals in 1970.

The group was formed after the 3 musicians from The Deviants (Paul Rudolph, guitar and vocals, Duncan Sanderson, bass and Russell Hunter, drums), sacked their singer and leader Mick Farren during a disastrous tour of West Coast USA. Prior to the tour these musicians had collaborated on the Think Pink solo album by Twink, former drummer of The Pretty Things, using the name Pink Fairies Motorcycle Club and All-Star Rock and Roll Band. Twink (drums), Farren (vocals), Steve Peregrin Took (guitar) and Twink's girlfriend Sally 'Silver Darling' Meltzer (keyboards) hooked up in October 1969 for one shambolic gig at Manchester University, billed as The Pink Fairies, and went on to record Farren's solo album, Mona – The Carnivorous Circus. Within a few months Twink had left, followed by Farren. In 1970, Twink recruited the remaining Deviants to a new Pink Fairies line-up.

An appearance at 1971's Glastonbury Festival led to them being given one side of the Glastonbury Fayre various artists triple album.
